Sunflower Leaves Black

[Irish-Digger]

Hello All, My Sunflower leaves have gone Black, what should I do please?

Do you mean totally shrivelled and black, or are they just black coloured?

Some varieities of sunflowers have very dark leaves, I'm growing one called (I think) Autumn King, it has really dark speckled leaves that have become darker overall as the plant has grown.

Hello Deb,

Thank you for your reply,
About half the leaves have been affected, and the blackness covers almost a third of the leaf.

Here is a picture of my sunflowers in May, I haven't got a more recent photo I'm afraid.....the leaves of the ones on the right are just beginning to look very sooty and speckled,  the newest leaves are affected first -are yours anything like this?





If just completely black at the edges, I would suspect frost damage..I would just pick those ones off and leave the rest.
